A series of Special Issues of Neuropharmacology celebrates the 40th anniversary of a seminal review on excitatory amino acid (EAA) receptors by two pioneers of the field – Dick Evans and Jeff Watkins. Brought together in the Department of Pharmacology at the University of Bristol in the 1970s, they forged a partnership that, through the synthetic chemistry prowess of Jeff Watkins, which provided novel agonists and antagonists for EAA receptors for Dick Evans's deft experimental studies, generated enormous insight into the multitude of actions of EAAs in the nervous system. Among many achievements from this time was not just the naming of the N-methyl- d -aspartate (NMDA) receptor, but also the demonstration of its antagonism by magnesium ions. Here, Dick and Jeff reflect upon those early halcyon days of EAA research, which, as these six 1 Special Issues of Neuropharmacology demonstrate, is very much alive and kicking. Bruno G.
